The other end is fixedly connected to the sliding block 24, and the sliding block 24 is slidably connected to the inner semicircular groove 11; the U-shaped plate 25 is fixed on the connecting rod 23; The shaft 31, the baffle 32, the spring 33 and the first sleeve 34, the end surface of the gear 21 is provided with a plurality of positioning holes 26; the bottom of the first vertical shaft 31 is penetrated in a positioning hole 26, the first The middle of the vertical shaft 31 fixes the baffle 32 , the top of the first vertical shaft 31 penetrates the first sleeve 34 , and the two ends of the spring 33 are respectively connected to the baffle 32 and the bottom surface of the first sleeve 34 .

The purpose of the inner semicircular groove 11 is firstly for sliding connection with the slider 24, and secondly, during use, the trainer's buttocks will stick closely to the semicircular plate formed by the inner semicircular groove 11, which is hinged at the end of the connecting rod 23. In the case of the bottom surface, the present invention avoids the friction between the buttocks and the hinged position during the separation of the trainer's legs; when in use, the trainer's legs need to keep the movement of separation for a long time, and the auxiliary personnel only need to lift the baffle 32, After the legs are separated to an appropriate angle, the baffle plate 32 is released, the first vertical shaft 31 is pushed into the positioning hole 26 by the spring 33, the gear 21 is locked, and the angle is maintained; it avoids the need for auxiliary personnel when the trainer is training split legs. It keeps pressing the trainer's legs, and at the same time avoids the problem of insufficient number of auxiliary personnel when there are many trainers, and improves the training efficiency.

Further, as shown in FIG. 3 , each control mechanism 3 further includes a tension line 35 , a second vertical shaft 36 and a second sleeve 37 , the end face of the connecting rod 23 close to the gear 21 is provided with a blind hole 27 , and the blind hole 27 communicates with the first The inner cavity of the sleeve 34; the top surface of the first vertical shaft 31 is connected to one end of the tension line 35, the other end of the tension line 35 is connected to the bottom wall of the blind hole 27, and the bottom of the blind hole 27 is connected to the inner cavity of the second sleeve 37, The inner cavity of the second sleeve 37 is sleeved on the second vertical shaft 36 , and the bottom surface of the second vertical shaft 36 abuts against the tension line 35 .

By pressing the upper end of the second vertical shaft 36 by the hand of the trainer, the lower end of the second vertical shaft 36 produces a pulling force on the tension line 35, and the tension line 35 produces a pulling force on the first vertical shaft 31, so that the first vertical shaft 31 can exert a pulling force on the gear 21.
